Can I help you , sir ?   Yes , I've been sitting here for a few minutes . I'm waiting for someone to put gas in my car .   I'm sorry , sir . But this is the self-service pump .   Self-service ?   Yes . You must fill up the car yourself .   Are you serious ?   Yes . Are you traveling here ?   Yes , I'm from Taiwan . I never heard of a gas station where you fill up your own car .   In America , most gas stations are like this .   Do I really have to do it ? I don't know how .   Well , since this is your first time , I will do it for you.But next time , if you want a full-service gas station , you should look at the sign .   What sign ?   Under the sign for the gas station , there will be a smaller sign that says Self-Serve or Full-Service.And some gas stations have both.But if they have both , some pumps will be self-serve and some will be full-serve.You have to look at the signs .   I see .
